Inputs
Input selection for the channels 1, 7 and 8. Channel 1 can be the front instrument input, or the
rear TRS jack, or both simultaneously. Channel 7/8 can be the front microphone input, or the
rear TRS jack, or both simultaneously.
Level In
Defines the reference level for the rear analog inputs 1-8.
Level Out
Defines the reference level for the rear analog outputs 1-8.
Instrument Options
Drive activates 25 dB additional gain for maximum sustain and brute distortion.
Limiter activates a soft-limiter with a threshold of –10 dBFS. Note: The Limiter can only be
switched off with input selection Front.
Speaker Emulation removes low frequency noise and cuts off higher frequencies.
Phantom Power
Phantom power (48V) can be selected for each microphone input separately.
SPDIF In
Defines the input for the SPDIF signal. 'Coaxial' relates to the RCA socket, 'ADAT2' to the sec-
ond optical TOSLINK input.
SPDIF Out
The SPDIF output signal is constantly available at the phono plug. After selecting 'ADAT2' it is
also routed to the second optical TOSLINK output. For further details about the settings ‘Pro-
fessional’, ‘Emphasis’ and ‘Non-Audio’, please refer to chapter 27.2.
Clock Mode
The unit can be configured to use its internal clock source (Master), or the clock source pre-
defined via Pref. Sync Ref (AutoSync).
AutoSync Ref.
Displays the current clock source and sample rate of the clock source.
Preferred Sync Ref / Input Status
Used to pre-select the desired clock source. If the selected source isn't available, the system
will change to the next available one. The current clock source and sample rate is displayed in
the AutoSync Ref display.
The automatic clock selection checks and changes between the clock sources Word Clock,
ADAT1, ADAT2, SPDIF and TCO (when using the optional TCO module).
Input Status indicates whether there is a valid signal (Lock, No Lock) for each input (Word
clock, ADAT1, ADAT2, SPDIF), or if there is a valid and synchronous signal (Sync). The Auto-
Sync Ref display shows the input and frequency of the current sync source.
